IMPROVEMENT IN ELEVATOR-BUCKETS.

Specification forming part of Letters Patent No. 2] 7,580, dated July15, 1879; application filed May 12, 1879.

To all whom it may concern Be it known that we, WILL H. BURDINE andCHRISTIAN D. OowerLL, both of Terre Haute, in the county of Vigo andState of In diana, have invented certain new and useful Improvements inElevator-Buckets; and we do hereby declare that the following is a full,clear, and exact description of the invention, which will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, which form a part ofthis specification, and in which Figure 1 is a perspective view. Fig. 2is a Fig. 3 is a vertical section on line :10 m, Fig. 2. Fig. 4 is aplan of the flat blank for forming the front section of the bucket; andFig. 5 is a similar View of the blank for forming in one piece the backand bottom sections. I

Similar letters of reference indicate corresponding parts in all thefigures.

This invention relates to elevator-buckets; and consists, first, inproviding buckets of this class with a lipped shield or guard upon thefront edge or dip, to prevent wear of the rim of the bucket; and,secondly, in the construction of the bucket from two blanks in such amanner as to economize material and at the same time produce a bucket ofgreat carrying capacity, substantially as hereinafter more fullydescribed, and pointed out in the claims.

In the drawings, A is the back, and B the bottom, of our improvedelevator-bucket,which are made in one piece from a sheet-metal blank ofthe configuration represented in Fig.

5-that is, having a square part or section, A,

and an adjacent semicircular part, B, made with two notches, b b, asshown. This semicircular part, when bent after the dotted line b b, Fig.5, at an angle of about eighty-five degrees, forms the bottom of thefinished bucket.

The curved front and sides 0 O O are also made from a flat blank, (shownin Fig. 4,) which is cut with a straight upper edge, having beveledcorners a, a, and a concave lower edge, e c, of lesser length, so as tomake the sides a c a c incline toward the bottom.

In forming the bucket from these blanks, the side and bottom edges ofthe back and bottom blank A B are struck up to form a flange after thedotted lines in Fig. 5, to which the sides and bottom of the blank 0 OO, after this has been bent into the requisite shape, are secured bysoldering, or in any other durable and suitable manner.

To increase the strength of the bucket, we use a band, D, of hoop orstrap iron, which is placed around the upper rim the upper flange, d d,of the back section A being turned down over it, as is also the upperrim, (4 a, of the front and sides 0 G O, as shown more clearly in thesectional view, Fig. 3. The overlapping ends of the band D are rivetedtogether upon the back of the bucket, and holes f f are punched throughthe back A and band D, by means of which the bucket may be riveted uponthe elevator band or apron.

IL is a shield or guarth nade of malheaple or cast iron, curved'toconform to the curvature of the front part of the bucket, upon the upperrim of which it is secured by rivets c. This shield or protector isprovided with a lip, g, which overlaps the central part of the upperedge or rim, as shown in Fig. 3, the upper edge of the guard Eprojecting above the edge of the bucket along its curved front part.

When the guard E has been worn down to the edge of the bucket, it mayeasily be removed by punching out the rivets, and a new guardsubstituted, as the bucket itself sustains no wear, and will be as goodas new.

Having thus described our invention, we

claim and desire to secure by Letters Patent of the United States- 1. Inan elevator-bucket, the edge-guard E, provided with the lip g,substantially as and for the purpose set forth.

2. An elevatorbucket composed of the square back part A and semicircularbottom part B made in one piece, and the bent front and side sections 0O 0, cut with a straight upper edge, inclined sides, and a concave loweredge, substantially as and for the purpose set forth.

In testimony that we claim the foregoing as our own we have heretoaffixed our signatures in presence of two witnesses.
